Description

Technical Field

[0001] The utility model relates to the technical field of automatic food conveyors, in particular to an automatic food conveyor. Background Technique

[0002] The food conveyor evolved from a goods lift. As the name implies, it is used for conveying between floors in places such as restaurants and hotels to improve efficiency and achieve energy conservation. By means of an electric lifting component, the motor can be started to automatically convey dishes without manual food transmission.

[0003] After retrieval, a Chinese patent with the publication number CN202320753829.3 discloses a lifting food conveyor that adopts a non-counterweight circumferential traction type. Specifically, a guide wheel, a traction wheel, a motor, and a steel wire rope are provided. The steel wire rope can be 1 or N. The steel wire rope is wound around the guide wheel and the traction wheel. When lifting and conveying dishes, the steel wire rope will not be overlapped and wound to cause wear. In addition, compared with the rubber synchronous belt traction, the steel wire rope is not easy to wear and weather, which improves the service life, safety, and durability of the food conveyor during use.

[0004] The above technical solution has the following defects. Although the structure of such an automatic food conveyor can drive the tray trough to lift through the steel wire rope, so as to achieve the function of automatic food transmission, in the actual use process, the stability of pulling the rope on only one side of the tray is poor, and unstable food transmission is likely to cause the soup and dishes to splash out. To further improve the stability during automatic food transmission, an automatic food conveyor is proposed. It is provided with two groups of driving wheels that can drive four groups of driven winding and unwinding wheels to wind and unwind the steel wire rope. The food transmission box can be driven to lift and convey food more stably through four steel wire ropes. Four groups of limiting steel cables are provided to limit the food transmission box at the four corners of the food transmission box, so as to prevent the food transmission box from shifting left and right during lifting, thereby improving the stability during the lifting process.

[0005] In view of this, this creation improves and solves the above problems, conducts intensive research and combines theoretical application, and finally proposes a technical solution with reasonable design and effective improvement of the above defects.

[0006] The information disclosed in this background technical section is only intended to deepen the understanding of the overall background technology of the utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art known to those skilled in the art.
